We are just finalising the design of our 24 Channel Servo Control SplashBridge.

Were using an LPC11U24, it has a built in USB Stack in ROM with a Mass storage device bootloader so updating code it as easy and dragging a hex file into a removable drive. The Cortex M0 will be controlled either via USB (HID or CDC) or SPI. We have allowed up to 5 chip select lines so that these boards can be stacked. This means you *could* control up to 120 servo's. This board also plugs in to our SplashBase board which then allows you to control the servo's via your network.

Actually I think we have 1 pin spare. Other IO is being used for the USB and Jtag header.We have allowed for 5 SPI chipselect lines out and in. So that this board can be a master or a slave on the SPI bus. Push another board on top ( the 2 black sockets each side are stacking connectors ) and you have another 24 Servos on the SPI bus.
